Oil Viscosity Recommendations
Posted 10 October 2003 - 11:56 AM
What is the preferred brand and weight of Oil for Subaru? What have you guys had luck with? We do get some very cold winters here on occassion as well.
Thanks for any help.

Here's what I do:
3 liters of 10-30 dino oil plus a quart of straight 40 grade (or 20-50 in very cold weather). Add some extra detergents at 2500 miles (stp or gunk), and change after 5000 mi.
But since you say you get "very cold winters" all 10-30 might be better, or even mix a quart of 5-30 in there.

In western NY I use 5w-30 full synthetic in the winter(november 1- april 1), and 10w-30 full synthetic in the "summer".
It snowed here last week. It was in the 70s today.

"Oil Viscosity For 1996 Subaru Vehicles Engine oil viscosity for all 1996 Subaru Legacy and Subaru Legacy Outback vehicles is specified as 5W-30 to improve fuel economy. This is a different viscosity rating than used in earlier production engines. At the present time, it is not recommended that a 5W-30 weight oil be used in Subaru vehicles calling for a different grade and viscosity. The oil used must meet the requirements for grade and viscosity as noted in the Owner s Manual."

5W-50 summer, temp up to plus 34 C
0W-40 winter, temp down to minus 20 C
No problems, over the last 60k miles and two years. Never any problems in other vehicles that I have treated similarly.
